It's hard to talk about Solange without bringing up Beyoncé, which is inevitable when your older sister is arguably the biggest pop star in the world. Playing a sold-out show at Fitzgerald's on Tuesday night, the 26-year-old brought her own low-key confidence in a vintage green-patterned dress, breaking out smooth dance moves with the energy of an indie star on the verge of a mainstream breakthrough.

Beyoncé may be fierce, but Solange is cool.

The tight, hourlong set was dominated by the bittersweet, '80s-inspired dance tracks on her "True" EP, starting with the deceptively breezy "Some Things Never Seem to (Expletive) Work" and the driving percussion of "Locked in Closets."

Despite Solange's recent rise to indie darling, the sold-out Houston crowd cheered when she dipped into her older tracks, never singing along more than to the Motown-ish "T.O.N.Y.," an ode to a one-night stand off 2008's "Sol-Angel and the Hadley St. Dreams."

While Solange's voice can sound like a slightly higher version of her sister's when she sings in her natural range, she's perhaps at her best when crooning in her rich, lovely falsetto on slower tracks like "Looks Good With Trouble."

She leaked that "Lovers in the Parking Lot" would be her next single (and she'll shoot the music video in Houston at Kings Flea Market on Griggs). It was "Parking Lot," combined with her effervescent lead single "Losing You," that marked the climax of her set, with the upstairs crowd jumping and dancing.

"Your energy is amazing," she said to the crowd, offering in return a couple of homecoming treats, including sliding into a cover of Selena's "I Could Fall in Love" at the end of "Don't Let Me Down" and closing the encore with her first-ever live performance of the Dirty Projectors' cover "Stillness Is the Move," hitting some Mariah Carey-style high notes in the process that earned cheers from the audience.

If her star keeps rising, the Fitzgerald's show could be Solange's last Houston performance in a venue of its size. Based on this show, she's ready for a bigger stage.
